Pastor Yong-sik Jin is a member of the Heresy Investigation Committee and director of the Heresy Investigation Counselling Center of The General Assembly of Presbyterian Church in Korea - one of the major Christian denominations with vested interests that are embroiled in controversy over heresy. As Pastor Jin is especially acknowledged by major religious denominations as an expert on heresy, the report is expected to cause a stir within the Christian community.

The Yong-Sik Jin Investigation Committee of IKCCAH announced: "It is an undeniable fact that there are distorted explanations of the Bible and dangerous heretical concepts within his explanation of revelations and soteriology. It is not right that he carries out this anti-cult duty and he must stop teaching counsellors against cults unless he fixes or changes his thoughts."

The committee emphasized that "This requires caution because people who have been educated by him may fall into the wrong ideas. Therefore, it is reasonable to disclose this information through the media and let people know so that there are no further victims."

The investigation committee spoke about the reason behind the investigation into Yong-sik Jin, saying: "Last year, we received a report that pastor Yong-sik Jin's revelation exposition and soteriology were non-Biblical and heretical and were asked to verify his teachings thoroughly. It is irrational and he must be warned against fulfilling anti-cult duties while he still has these ideas. The purpose of our investigation into Yong-sik Jin is to let him reveal his distorted ideas and fix them in order to help other churches discern and protect themselves."

Pastor Yong-sik Jin is a famous Heresy Investigation counsellor within the Korean Christian community. He has acted as vice-chairman of the Heresy Investigation Response Committee of Christian Council of Korea and the director of the Heresy Investigation Counselling Center of General Assembly of Presbyterian Church in Korea. He is a current member and counselling director of the Cult and Heresy Damage Response Investigation and Research Committee.

But, in actuality, controversy over his qualifications has continued.

In 2013, CCK (Christian Council of Korea) labelled pastor Yong-sik Jin, chairman of Christian Cult Counselling of Korea, as a cult and requested that the General Assembly of Presbyterian Church in Korea dismiss him. Pastor Jin was a member of the Seventh-Day Adventist Church which CCK had defined as heretical. CCK pointed out that he had been working without verifying his qualifications. CCK also raised suspicions about how Pastor Jin had enrolled at Chongshin University given that he had recorded himself as an 'elementary school drop-out' within his educational background section.

Pastor Yong-sik Jin is a typical pastor who gains monetary benefits from coercive conversion against members of Shincheonji church under the justification that 'Shincheonji is defined as a cult by CCK', like Pastor Hyeon-ook Shin who also is famous for coercive conversion.

However, Pastor Jin had been given a 10-month sentence of imprisonment with two years’ probation on suspicion of having violated the law through acts of violence including 'Coercive imprisonment of people at night' and 'Abetting confinement' from the Supreme Court in October of 2008. In 2012, pastor Jin sued human rights activists who had been involved in public campaigns calling pastor Jin a 'Family Destroyer' on grounds of defamation, but he lost the case.
